ATTORN EY Jan. 11 9, 1965 Filed Jan. 10, 1962 H. KLOSTERMANN APPARATUS FOR STICKING PAPER STRIPS AND HEAD BANDS OR BACKING GAUZE ONTO BOOK-BLOCK SPINES Maw ATTORNEY 4 Sheets-Sheet 4 3,166,463 Patented Jan. 19, 1965 7 claims; cl. tee-477 The present invention relates to apparatus for sticking paper strips and head bands or backing gauze onto bookblock spines. In bookbinding the term head band designates a variously coloured woven band, small sections of which are secured in pairs lengthwise over the width of the book at both ends of a book-block spine for the purpose of decoration, securing usually being by gluing. Machines for fixing the head bands to book-block spines are known per se, wherein the head bands are first glued to a paper strip or the like and then together with this strip are applied to the spine which has been previously covered with glue. These known machines are operated either by mechanical or pneumatic means and the sticking is carried out from below on to the book-block which can be either stationary or moving.

When placing the head bands, the problem always arises as to how the paper or gauze strips with the head bands can always be applied accurately to the moving spines, in order that the part of the head band protruding beyond the spine is absolutely equal in each book.

It is an object of the invention to solve this problem and to make a simple and very reliable apparatus by means of which the book-blocks or book fillers will be fitted with paper strips and laterally applied head bands always having the same position during the passage through the machine.

With this end in view, the invention consists in apparams for mechanically sticking paper strips and head bands or backing gauze to book-block spines during the continuous passage of the book-blocks or book fillers in a longitudinal direction, said device being arranged beneath two parallel and constant speed transport members for the book-blocks or book fillers, wherein a vertical carrier is caused to move upwardly and downwardly when the moving book-blocks or book fillers contact electrical contact means and thereby activate a lifting magnet, said vertical carrier having a carrier which moves horizontally therein to and fro in the direction of movement of the bookblocks or book fillers and having a guide plate which contacts the passing book-blocks or book fillers and which at the same time constitutes a rest for a backstrip which is already cut up and lying on the horizontal carrier, so that the back-strip can be pressed on to the book-block spines in apredetermined position by means of said guide plate and two further stop means and which moves a path member in the direction of movement of the book-block or book filler under constant pressure of the horizontal carrier, together with the book-block or book filler.

Preferably a cutting device is arranged parallel to the horizontal carrier, the cutting level of said device being between upper and lower blades thereof and forming a plane of reference for a lateral book-block or book filler United States Patent (Mike edge and the back-strip. In order to apply the backing vantage that the book-blocks or book fillers can pass in front of the machine without stopping, the various gluing, sticking and pressing stations being grouped together. Machines having the apparatus according to the invention can be fed at random, i.e. do not have to be fed at specitied intervals of time, thus leading to far higher eiliciency.

In order that the invention may be more clearly understood, reference will now be made to the accompanying drawings, which show one embodiment thereof by way of example, and in which:

FIGURE 1 shows a front View of a complete machine, FIGURE 2 shows a front view of part of the machine of FIGURE 1, in the inoperative position,

FIGURE 3 shows a cross-section along the lines A--B of FIGURE 2, and

FIGURE 4 shows a view similar to FIGURE 2, but

in the operative position.

Referring to the drawings, the book-blocks or book fillers 2 rest on the feed plate or conveyor belt 1 by their backs, and are held by two parallel conveyor chains 3 and transported through the machine at a constant speed in the direction of the arrow 4. In this manner the book-blocks or book fillers pass in front of the various stations such as the gluing station 5, where the spines are covered with a layer of glue, the sticking station 6, in which the paper strips with the two head bands are applied to the spines, and the pressing station 7.

These individual units are switch on and off by means of the moving book-block 2 travelling through the ma chine, which cooperates with electrical contact makers 37 or photoelectric cell means 37a. (Such electrical contact makers are well known in the art and are often used in known bookbinding machines. Illustrative of such electrical contact makers are parts 230, 235, 253 and 254 of U3. Patent No. 2,646,104 which discloses a bookbinding machine.) When a moving book block or book filler depresses the plunger of electrical contact maker 37 or enters into the lightpath of the photoelectric cell means 37a, the electrical circuit for the electro-magnet 31 is closed and the latter moves the vertical carrier 25 via the lever 32 towards the moving book-filler 2. The aforementioned electrical contact maker 37 or photoelectric 37a may also electrically sequentially activate the upper blade 10 and transport roller 14 which by means of electric motor means 8 (not shown in detail) feed the material 18 onto the horizontal carrier 24 and then cut it. Alternatively the transport roller 19 can be activated by means of a second electrical contact maker 38, 39 (see FIG. 3), which upon retraction of the plunger of magnet 31 cause an electrical circuit for the activation of the transport roller 14 to be closed.

The sticking device has a servo-drive motor 8 which operates the advance of the paper strip and a transverse cutting device by means of a pin clutch- 9 and other additional driving means. The pin clutch 9 is operated for rotation only after the book-block or book-filler 2 has released the electrical switch 37 or 37a and then the upper blade is brought upwards by means of cam 11, crossbeam 12 and tie-rod 13 in order to open a passage for the material to be adhered. In the short period that the upper blade 10 remains in the raised position, the material 18 to be adhered (paper with head band or also backing gauze) is moved forward by the transport rollers 14 and pressure rollers 15 in the direction of arrow 16 around the dimension of the spine which has been set by crank 17. Upper blade 10 then drops again and remains, after cutting has been effected and the pin clutch has rotated for one revolution, in the lower position as a unidirectional applicator for the cut spine strips.

This applicator edge is the plane of reference 19 for the edge of the book-block of book-filler, which means that the centre line 20 of the chain drive remains unchanged even if the thickness of the book is changed, and alteration need only be carried out to chain drive 21. The angle member 22 of the applicator, which is only shown in FIGURE 3, may also be adjusted to provide a second limiting means for the cut spine strip.

If backing gauze also is to be adhered to the spine by the sticking device 6, which gauze should be cut wider than the width of the book, as is known, and protrude on each side of the width of the book, then the sticking device 6 is moved along rails 36 (FIGURE 1) in the direction of the arrow 34 (FIGURE 3) so that the plane of reference 19 of the material to be adhered, backing gauze in this case, is displaced by the distance set from the edge of the book-block or book-filler.

The spine strip is now limited on both sides on carrier 24, the upper part 23 of which should preferably consist os soft rubber or the like, in order that it better fits the rounding of the bookback during the sticking operation. Carrier 24 runs freely on moving ball bearings 33 and can only be moved horizontally in relation to the vertically operating carrier 25.

The lug 26 of horizontal carrier 24 is held on the starting roller 28 in the normal position of the device as shown in FIGURE 2, by means of the tension produced by tension spring 27, said starting roller 28 being secured to the middle partition 29 of the sticking device. The third part of the sticking device 6 is the guide plate 39 which is secured to the horizontal carrier 24. By means of this arrangement, sliding of the sticking strip 18 in the direction opposite to that of arrow 4 is prevented, and it furthermore has the advantage that an expensive suction device, as is necessary in known machines, can be dispensed with.

After book-block or book tiller 2 has released the contact 37, 37a and actuated the E-magnet 31 in order that the vertical carrier can move at high speed by means of crank 32, the horizontal carrier 24 is drawn by the power of spring 27 in the direction of arrow 4, as a result of which guide plate 39 is applied against the bookblock or book filler 2 in order that exact application is ensured. Carrier 24 can then move with book-block 2 in the direction of arrow 4 until the lug 26 abuts the starting roller 28 so that on downward movement of the vertical carrier 25 by the oblique guiding of lug 26 against the spring 27, the horizontal carrier 24 is once more returned to its normal position. The electrical switching operations follow one another so closely that when magnet 31 is cut off, when the vertical carrier 25 is in its upper position, the pin clutch 9 is simultaneously operated in order to bring forward the material to be adhered for the next book-blocker book fiiler in the direction of arrow 16, as has already been described, said material being cut and limited by blade 10.

The invention is not restricted to the embodiment which has been described and illustrated in the accompanying drawings. Modifications may be made without departing in any way from the scope of the invention. For example, the movement of carrier 24 may be carried out by cam control, pneumatic, hydraulic or other means instead of the spring.
